后台返回的是一个html文本, iOS 使用label 解析方法

举例如下:

let label = UILabel(frame: CGRect.init(x: 10, y: 0, width: 500, height: 100));
    
let str =  "恭喜获得<span style='color:red; font-size:30px'>8.1元</span> 奖励";

let attribstr = try! NSAttributedString.init(data:(str.data(using: String.Encoding.unicode))! , options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil);
            
label.attributedText = attribstr
            
self.view.addSubview(label)

效果图如下
